Can I Run GLM-4 9B on Apple M1 Pro?
Written by Jakub Rusinowski · Last updated July 12, 2026
Yes. GLM-4 9B needs 7.4 GB at 8K context (5.4 GB weights + 2 GB KV cache/overhead) at Q4_K_M and the Apple M1 Pro has 24 GB usable, leaving about 16.6 GB of headroom, at roughly 17 tok/s (estimated) with room for up to 64K of context.

GLM-4 9B on the Apple M1 Pro: VRAM by quantization

|---|---|---|---|---|
| F16 | 20 GB | ✓ Yes | 32K | — |
| Q8_0 | 11.6 GB | ✓ Yes | 64K | — |
| Q6_K | 9.4 GB | ✓ Yes | 64K | — |
| Q5_K_M | 8.4 GB | ✓ Yes | 64K | — |
| Q4_K_M | 7.4 GB | ✓ Yes | 64K | — |
| Q3_K_M | 5.8 GB | ✓ Yes | 64K | — |
| Q2_K | 5 GB | ✓ Yes | 64K | — |
Assumes an 8K-token context with an f16 KV cache, on an estimated architecture — this model publishes no config we can read. A longer window needs more; a quantized KV cache needs less. “Max context” is the largest window that still fits in 32 GB of unified memory. Figures are estimates from parameter count, quantization and memory bandwidth — the analyzer lets you tune KV-cache quant and context.
Context costs VRAM too. At Q4_K_M on the Apple M1 Pro: 8K 7.4 GB · 32K 11.1 GB · 125K 25.1 GB ✗. Past 125K it no longer fits 32 GB — a q8_0 KV cache buys roughly half of that back, which the calculator will price for you.
What to do next
Nothing to change — run it at Q4_K_M. If you want more capability, check whether the next size up also fits.
